Evergy, Inc. Nonqualified Deferred Compensation Plan, effective as of June 4, 2018

Kansas City Power & Light Company ("KCPL") adopted the Kansas City Power & Light Supplemental Executive Retirement and Deferred Compensation Plan effective November 2, 1993 (the "Original Plan"), to provide opportunities for selected employees and members of KCPL's Board of Directors to defer the receipt of compensation. As part of a corporate restructuring and effective as of October 1, 2001, the Original Plan was divided into two separate plans, the "Great Plains Energy Incorporated Nonqualified Deferred Compensation Plan" (the "Frozen NQDC Plan") and the Great Plains Energy Incorporated Supplemental Executive Retirement Plan (the "Frozen SERP").

As a result of the enactment of the American Jobs Creation Act of 2004, which, in part, created a new section of the Internal Revenue Code ("Code Section 409A") governing and requiring changes to nonqualified deferred compensation plans, Great Plains Energy Incorporated (i) froze the Frozen NQDC Plan (a copy of which is attached as Appendix B) as of December 31, 2004 such that no new participants entered the Plan and no new amounts (other than Earnings) accrued under the Plan after December 31, 2004 and (ii) adopted the Great Plains Energy Incorporated Nonqualified Deferred Compensation Plan (As Amended and Restated for I.R.C. § 409A) which plan, except for those changes required by Code Section 409A generally mirrored the terms of the Frozen NQDC Plan.

As a result of and effective upon the consummation of Great Plains Energy Incorporated's merger into Evergy, Inc., the Great Plains Energy Incorporated Nonqualified Deferred Compensation Plan (As Amended and Restated for I.R.C. § 409A) was restated to reflect such merger as this Evergy, Inc. Nonqualified Deferred Compensation Plan (the "Plan").

The Plan governs the payment of, and all administrative aspects related to amounts that (1) were not accrued and vested as of December 31, 2004 under the Frozen NQDC Plan and (2) have been or are contributed to this Plan on or after January 1, 2005. Certain operations of the Plan between December 31, 2004 and December 31, 2007, including those operations in 2005 memorialized in Appendix A, however, were completed in accordance with IRS Notice 2005-1 and in "good faith" compliance with the proposed Treasury Regulations issued under Code Section 409A.

Generally, the Plan was amended and restated effective January 1, 2005. However, several features, terms and conditions were effective January 1, 2008. These include: (1) the definition of Specified Employees; (2) the removal of the vesting schedule applicable to Company matching contributions; and (3) the changes made to Article III, relating to the Capital Accumulation Excess Benefit Provision. No duplication of benefits is to have resulted from the freeze of the Frozen NQDC Plan, the amendment and restatement of the Plan effective January 1, 2005 or the renaming of this Plan as of the Merger Effective Date. All existing elections under this Plan shall continue in effect without change and apply as elections under the Plan.

2.1    Deferral Elections. Before the beginning of any calendar year, a Participant may elect to defer the receipt of:

If the Participant desires to make such an election, the election must be in writing on a form provided by the Company, and may indicate an election to defer a fixed percentage of up to 50 percent of Base Salary, and/or 100 percent of director's fees or any Incentive Awards. Alternatively, the Participant may elect to defer a fixed dollar amount of Base Salary and/or any Incentive Awards in increments of $1,000, with a minimum deferral of $2,000 and a maximum deferral of an amount equal to 50% of Base Salary and 100% of director's fees or any Incentive Awards. An individual who first becomes a Participant in this Plan (and is not otherwise eligible nor has been eligible to participate in any other similar type of Plan that would be aggregated with this Plan under Code Section 409A) during a year may make a deferral election for the balance of the year in which the employee becomes a Participant, provided the election is made within 30 days after the day on which he or she becomes a Participant.

An election to defer compensation under this Article II applies only to compensation earned subsequent to the date the election is made. An election to defer compensation will be effective only for the year, or portion of the year, for which the election was made, and may not be terminated or changed during such year or portion of such year. If the Participant desires to continue the same

election from year to year, he or she must nevertheless make an affirmative election each year to defer compensation.

2.2    Contents of Deferral Election. A Participant's deferral election must indicate, with respect to amounts deferred pursuant to the election, a distribution event in accordance with Section 2.6 and the form of payment alternative in accordance with Section 2.7.

2.3    Separate Accounts. A separate account will be established for each Participant who defers compensation under this Article II. The Company will credit deferred Base Salary to the Participant's account each month at the time the nondeferred Base Salary is paid to the Participant. The Company will credit the Participant's account with a deferred Incentive Award annually at the time the Incentive Award is payable. Neither the Participant nor his or her designated beneficiary or beneficiaries has any property interest whatsoever in any specific Company assets as a result of this Plan.

2.4    Earnings Credits. The earnings rate each year upon which gains or losses on a Participant's account are credited (hereinafter "Earnings") will be a reasonable rate of interest based on the Company's weighted average cost of capital. The Earnings will be credited or debited to a Participant's account on a monthly basis, or at such other time or times as the Committee may determine. Earnings will continue to be credited to the balance of a Participant's account during the payout period elected pursuant to this Article II. The Earnings attributable to compensation deferred pursuant to a particular deferral election will be payable according to the same terms, conditions, limitations, and restrictions applicable to the compensation deferred pursuant to the deferral election. Any remaining payments will be re-computed annually to reflect the additional Earnings.

2.5    Company Contributions.

Employee Savings Plan and this Plan exceed 6% of the Converted Participant's or Post-2007 Participant's Base Salary in any given year.

Any matching contributions under this Plan will be credited to the Participant's account on a monthly basis. For Stationary Participants, the matching contributions and Earnings thereon shall be subject to the following vesting schedule:

For Converted Participants and Post-2007 Participants, all matching contributions and Earnings thereon, including all matching and Earnings accrued before January 1, 2008, are 100% vested.

conditions and/or allocation conditions with respect to such additional contributions. No Participant shall have a right to compel the Company to make a contribution under this Section 2.5(b) and no Participant shall have the right to share in the allocation of any such contribution for any year unless selected by the Board, in its sole discretion. At the time any such additional contribution is made, the Board may provide that the additional amounts are to be paid at the same time as other amounts deferred under this Plan are paid to the Participant or a different time (in all cases compliant with Code Section 409A) as established by the Board.

2.6    Permissible Distribution Events A Participant may elect to defer receipt of amounts deferred pursuant to a deferral election until one of the following:

In all cases if no distribution event has occurred on the date of the Participant's death, the Participant's death will be the distribution event. If a Participant fails to designate a distribution event and the Participant is not a Specified Employee at the time of the Participant's Separation from Service, payment of amounts deferred pursuant to the Participant's deferral election will be

made (in the case of a lump sum) or commence (in the case of installments) on the 90^th day after the Participant's Separation from Service. If a Participant fails to designate a distribution event, the Participant is a Specified Employee at the time of the Participant's Separation from Service and the Separation from Service is not on account of the Participant's death, payment of amounts deferred pursuant to the Participant's deferral election will commence on the first day of the 7^th month after the month in which the Participant Separates from Service.

2.7    Permissible Forms of Payment. A Participant's deferral election must indicate the manner in which the amounts deferred pursuant to the election are to be paid upon a distribution event other than on account of a Participant's death. Upon a Participant's death, the form of payment is governed by Section 2.8(b), (c) and (d). Subject to this Section 2.7, the Participant may choose to have such amounts paid:

Notwithstanding a Participant's deferral election, single lump-sum payments will always be made to Participants (I) whose annual installments (regardless of whether such installments are being paid over 5, 10 or 15 years) will be less than $5,000 per year or (II) who Separate from Service with the Company before attaining age 50. If a Participant fails to make an

election concerning the form of payment within the appropriate period of time, the payment will be made in a single lump sum.

Subject to Section 4.12, payments under this Article on account of deferral will be paid in full if the lump-sum option is chosen, or will begin to be paid in annual installments if an installment payment option is chosen, on the 30^th day following the day the event occurred giving rise to the distribution, as elected by the Participant. If, on such 30^th day, it is not administratively practicable to make or commence the payment(s), the payment(s) shall be made or commence as soon as administratively practicable.

Following the close of each year, or as soon thereafter as practicable, the Participant or the Participant's designated beneficiary or beneficiaries shall receive a statement of the Participant's deferred compensation account as of the end of such year.

2.8    Payment to Designated Beneficiaries.

amounts credited to the Participant's account will continue to be paid to the Participant's beneficiary or beneficiaries at the same times and in the same form as the amounts were being paid to the Participant.

2.9    Subsequent Elections. The Committee, in its sole discretion, may permit a Participant, with respect to a distribution event, to later change the Participant's election as to when payment of benefits under this Plan with respect to such event would be made or commence and change the selected form of payment; provided, however, that: (a) the subsequent election is not effective until, at the earliest twelve months before it is to take effect; (b) other than with respect to payment on account of a Participant's death, the change results in a deferral of payment of at least five years from the earliest date the benefits, absent such a subsequent election, otherwise would have been paid or commenced on account of such event; and (c) where the Participant has elected payment after a specific number of years, the subsequent deferral election is made at least twelve months before the initial payment was scheduled.

2.10    409A Transition Election. All Participants in the Plan were permitted to amend their then current elections relating to both timing and form of payment before December 31, 2008.

3.1    Effective January 1, 2008, no additional amounts were contributed to Participant's CAP Excess Benefits Account under the Plan. From January 1, 2005 through December 31, 2007, amounts were credited to a Participant's CAP Excess Benefit Account in accordance with the same manner as provided for in Section 3.1 of the Frozen NQDC Plan.

3.2    Benefits under the Participant's CAP Excess Benefit Account will be paid to the Participant as follows:

4.1    Plan Amendment and Termination. The Board may, in its sole discretion, terminate, suspend, or amend this Plan at any time or from time-to-time, in whole or in part. However, no amendment or suspension of the Plan may affect a Participant's right or the right of a beneficiary to vested benefits accrued up to the date of any amendment or termination. In the event the Plan is terminated, the Committee will continue to administer the Plan until all amounts accrued and vested have been paid. In no event may the termination of the Plan result in distributions of benefits under the Plan unless such distribution on account of Plan termination would otherwise be permissible under Code Section 409A.

4.2    No Right to Employment. Nothing in this Plan gives any Participant the right to be retained in the service of the Company, nor will it interfere with the right of the Company to discharge or otherwise deal with Participants without regard to the existence of this Plan.

4.3    No Administrator Liability. Neither the Committee nor any member of the Board nor any officer or employee of the Company may be liable to any person for any action taken or omitted in connection with the administration of the Plan unless attributable to his or her own fraud or willful misconduct; nor may the Company be liable to any person for any such action unless attributable to fraud or willful misconduct on the part of a director, officer or employee of the Company.

4.4    Unfunded Plan. This Plan is unfunded, and constitutes a mere promise by the Company to make benefit payments in the future. The right of any Participant, spouse, or beneficiary to receive a distribution under this Plan will be an unsecured claim against the general assets of the Company. The Company may choose to establish a separate trust (the "Trust"), and to contribute to the Trust from time to time assets to be held therein, subject to the claims of the Company's creditors in the event of the Company's insolvency, until paid to Plan Participants and beneficiaries in the manner and at the times as specified in the Plan. It is the intention of the Company that the Trust, if established, constitutes an unfunded arrangement, and will not affect the status of the Plan as an unfunded Plan maintained for the purpose of providing deferred compensation for a select group of management or highly compensated employees for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended. The Trustee of the Trust will invest the Trust assets, unless the Committee, in its sole discretion, chooses either to instruct the Trustee as to the investment of Trust assets or to appoint one or more investment managers to do so. The Committee may consult with Participants concerning the investment of Trust assets, but will reserve the right to invest and reinvest such assets in the manner it deems best.

4.5    Nontransferability. To the maximum extent permitted by law, no benefit under the Plan may be assignable or subject in any manner to alienation, sale, transfer, claims of creditors, pledge, attachment, or encumbrances of any kind.

4.6    Participant's Incapacity. Any amounts payable under the Plan to any person under legal disability or who, in the judgment of the Committee, is unable properly to manage his or her financial affairs, may be paid to the legal representative of that person or may be applied for the benefit of that person in any manner which the Committee may select.

4.7    Withholding. Any amounts paid to the Participant will be subject to income tax withholding or other deductions as may from time to time be required by federal, state, or local law.

4.8    Plan Administrator. The Plan shall be administered by the Committee or its designee, which may adopt rules and regulations to assist it in the administration of the Plan.

4.9    Claims Procedures. A request for a Plan benefit shall be filed with the Chairperson of the Committee or his or her designee, on a form prescribed by the Committee. Such a request, hereinafter referred to as a "claim," will be deemed filed when the executed claim form is received by the Chairperson of the Committee or his or her designee.

The Chairperson of the Committee or his or her designee shall decide such a claim within a reasonable time after it is received. If a claim is wholly or partially denied, the claimant will be furnished a written notice setting forth, in a manner calculated to be understood by the claimant:

The notice will be furnished to the claimant within 90 days after receipt of the claim by the Chairperson of the Committee or his or her designee, unless special circumstances require an

extension of time for processing the claim. No extension will be for more than 90 days after the end of the initial 90-day period. If an extension of time for processing is required, written notice of the extension will be furnished to the claimant before the end of the initial 90-day period. The extension notice will indicate the special circumstances requiring an extension of time and the date by which a final decision will be rendered.

If a claim is denied, in whole or in part, the claimant may appeal the denial to the full Committee, upon written notice to the Chairperson thereof. The claimant may review documents pertinent to the appeal and may submit issues and comments in writing to the Committee. No appeal will be considered unless it is received by the Committee within 90 days after receipt by the claimant of written notification of denial of the claim. The Committee shall decide the appeal within 60 days after it is received. However, if special circumstances require an extension of time for processing, a decision will be rendered as soon as possible, but not later than 120 days after the appeal is received. If such an extension of time for deciding the appeal is required, written notice of the extension shall be furnished to the claimant before the commencement of the extension. The Committee's decision will be in writing and will include specific reasons for the decision, written in a manner calculated to be understood by the claimant, and specific references to the pertinent Plan provisions upon which the decision is based.

4.10    Deliverables. Each Participant will receive a copy of the Plan and, if a Trust is established pursuant to Section 4.4, the Trust, and the Company will make available for inspection by any Participant a copy of any rules and regulations used in administering the Plan.

4.11    Binding Effect. This Plan is binding on the Company and will bind with equal force any successor of the Company, whether by way of purchase, merger, consolidation or otherwise.

4.12    Delay for Specified Employees. Notwithstanding any other provision of this Plan to the contrary:

4.13    Severability. If a court of competent jurisdiction holds any provision of this Plan to be invalid or unenforceable, the remaining provisions of the Plan shall continue to be fully effective.

4.14    I.R.C. § 409A. This Plan is intended to meet the requirements of Section 409A of the Code and may be administered in a manner that is intended to meet those requirements and will be construed and interpreted in accordance with such intent. All payments hereunder are subject to Section 409A of the Code and will be paid in a manner that will meet the requirements of Section 409A of the Code, including regulations or other guidance issued with respect thereto, such that the payment will not be subject to the excise tax applicable under Section 409A of the Code. Any provision of this Plan that would cause the payment to fail to satisfy Section 409A of the Code will be amended (in a manner that as closely as practicable achieves the original intent of this Plan) to

comply with Section 409A of the Code on a timely basis, which may be made on a retroactive basis, in accordance with regulations and other guidance issued under Section 409A of the Code.

4.15    Governing Law. To the extent not superseded by the laws of the United States, this Plan shall be construed according to the laws of the State of Missouri.

Notwithstanding any other provision of this Plan or any election that may have been made by a Participant to the contrary, if a Participant who Separates from Service in 2005 elected to receive either a one-time, single-sum payment of the Participant's entire account or an annuity or series of payments, (i) all amounts credited to the Participant's account before 2005 are to be paid in accordance with such election, and (ii) all amounts credited to the Participant's account during 2005 will be paid in one-time, single-sum payment in 2005.
